Abstract
An erosion, sediment and pollution control product comprises a geotextile which includes at least 10% non-plastic non-biomass based inert threads, in particular basalt or glass threads, and cellulose based filler within the tubular geotextile. The geotextile may be knitted. A method of making a tubular knitted geotextile comprises the steps of: supplying non-plastic, non-biomass based inert threads, such as basalt or glass threads, to a circular knitting machine and knitting a tubular substrate which includes at least 10% non-plastic non-biomass based inert threads.
Claims11
A tubular geotextile configured for forming an erosion, sediment and pollution control product including at least 10% non-plastic, non-biomass based inert threads, wherein the geotextile is knitted, wherein the tubular geotextile has an effective tube diameter from about 5 inches to about 32 inches, wherein the tubular geotextile has openings therein with an effective average opening size of about ⅛ inch to about ½ inch, wherein the non-biomass based inert threads include one of basalt threads and glass threads and wherein the basalt or glass threads uses filaments with diameters less than 20 microns and wherein the tubular geotextile forms the netting of a filter sock.
An erosion, sediment and pollution control filter sock product comprising:
- A tubular geotextile including at least 15% non-biomass based inert threads wherein the tubular geotextile has openings therein with an effective average opening size of about ⅛ inch to about ½ inch, wherein the geotextile is knitted, wherein the tubular geotextile has an effective tube diameter from about 5 inches to about 32 inches, wherein the non-biomass based inert threads include one of basalt threads and glass threads and wherein the basalt or glass threads uses filaments with diameters less than 20 microns;
- and
- A cellulose based filler within the tubular geotextile.
